Special Features and Pump Benefits
Automatically Removes Air and Vapour
Whenever air or vapour is present at the start of the pumping operation – or when there is a loss of suction because of air or vapour during pumping – the priming pump automatically moves air and vapour from the suction line to the discharge line. Once the flowing liquid from the centrifugal portion of the fuel pump builds up sufficient pressure in the discharge system, the priming pump stops.
Here is a more in-depth look at how the priming system works:
Full Priming Position
When air or vapour is in the suction line, the spring is able to hold the priming pump in full air pumping position.
As the pump evacuates air and vapour from the lines, liquid pressure builds up on the underside of the sliding priming pump housing, moving it toward neutral.
When air and vapour are removed, liquid pressure equalises spring pressure and the priming pump automatically slides into neutral…..where it remains until air and vapour appear again in the system.
Roto-Prime pumps are actually two pumps in one. The small powerful vane-type pump within the main centrifugal housing can prime an absolutely dry 100mm line with zero back pressure in approximately 6 seconds per metre without initial manual priming.
